Yes, it might be helpful to have a code snippet to demonstrate the
configuration for partition discovery.

The docs correctly say:
{quote}
To enable it, set a non-negative value for
+flink.partition-discovery.interval-millis+ in the _provided properties config_
{quote}
So it should be set in the Properties that are passed in the constructor of
FlinkKafkaConsumer.
I had somehow assumed that this should go to flink-conf.yaml (maybe because it
starts with "flink."?), and obviously the FlinkKafkaConsumer doesn't read that.
A piece of example code might've helped me avoid this mistake.
This was discussed on the user mailing list:
